The set command enables the supported 3GPP Release 14 features on the modem.
The %REL14FEAT command is allowed only before activating the
modem with the +CFUN=1 command. If the feature configuration needs to be
changed, the modem must first be set to flight mode with the +CFUN=4
command. Otherwise, the command returns ERROR.
The command configuration is
stored to Non-volatile Memory (NVM) approximately every 48 hours and when the modem is
set to minimum functionality mode with the +CFUN=0
command. Values stored by the user can be
overwritten by operator settings.
- All 3GPP Release 14 features are disabled by default.
- Enabling Narrowband Internet of Things (NB-IoT) dual Hybrid Automatic Repeat Request (HARQ) enables also maximum TB size enhancement.
- Enabling Release Assistance Indication (RAI) requires feature activation with the %RAI command.
Syntax:
%REL14FEAT=<mac_inact_monitor_support>,<as_rai_support>,<NB_dual_harq_support>,
<NB_max_TB_size_support>,<interf_cmm_intraf_rsrq>- +CME ERROR code
- 518 – Not allowed in active state.
The set command parameter and its defined values are the following:
- <mac_inact_monitor_support>
- 0 – MAC inactivity monitoring not supported
- <as_rai_support>
- 0 – Access stratum RAI not supported
- <NB_dual_harq_support>
- 0 – Narrowband dual HARQ not supported
- <NB_max_TB_size_support>
- 0 – Narrowband maximum transport block size not supported
- <interf_cmm_intraf_rsrq>
- 0 – Inter-frequency connected mode and intra-frequency Reference Signal Received Quality (RSRQ) measurements not supported
The following command example sets support for MAC inactivity monitoring and inter-frequency connected mode and intra-frequency RSRQ measurements mode:
AT%REL14FEAT=1,0,0,0,1
